The CMF of 0.86 used to reduce right-angle crashes targets which crash type?

Explanation:
Crash Modification Factor (CMF) shows how much a safety measure changes crash frequency. A value below 1 means fewer crashes after implementation. A CMF of 0.86 indicates a 14% reduction in the specific type of crash that the measure is designed to affect. In this case, that CMF is aimed at reducing right-angle crashes—those perpendicular, crossing conflicts that occur at intersections when two traffic streams intersect. So the targeted crash type is right-angle crashes. Measures that reduce these crashes usually modify intersection geometry or operation to lessen crossing conflicts, such as roundabouts or signal/laning changes.
